Abstract
A repeater for PCM or digital transmission systems includes, in addition to the usual primary feedback control loop, a secondary feedback control loop having a low-pass filter and a peak detector to derive a control signal for a controllable impedance in the equalizer circuit. This control loop optimizes the repeater performance for different cable types and characteristics with regard to the low frequency energy content of the eye diagram.
